OK! USA's insider reportedly discovered that Pitt, 54, reached out to Aniston, 49, following her separation from Justin Theroux.
'It was Brad's idea to get together and talk about a potential project,' a source outrageously tells.
'He invited her over to his house and she saw that old charm she loved so well. She realised how much she had actually missed him.'
The source adds the pair have been regularly getting together in LA, splitting time between each other's homes.
'Jen always imagined they would have a family together, and it finally seemed like the time was right to make that dream a reality,' an insider adds.
According to sources close to the couple, it was during one of their romantic get-togethers that Jen surprised Brad with a proposal - to have a baby with her.
'Of course he agreed', the source sensationally reveals.
'Those are the words he long to hear her say years ago. Brad said he would be thrilled to give her that gift.'
According to OK! USA's sensational report, the pair are blissfully planning the next steps.
'They've been discussing moving back in together, whether into Brad's place or a new home,' a source shares.
'Jen feels she's exactly where she's supposed to be!'
Neither Jen or Brad have responded to OK! USA's bombshell report.
